Cooke aviar 6in f 4.5 coverage.

hi,

do any of you know if taylor hobson cooke aviar anastigmat f/4.5 would cover 5x7 format?

and second any ideas aaboy 13in cooke anastigmat process lens series VB is it a good lens?

thanks

6" Aviar cover 5x7? It seems not. See http://www.cameraeccentric.com/html/info/cooke_2.html

yes

The 13" f8 Vb process lens probably doesn't cover 10x8 at Infinity, it's listed as covering 10x8 at half size and more at 1:1 (full size). The plain Series V 13" f8 is a general purposea commercial lens and covers 10x8 at infinity at full aperture.
